Im stumped on this code, It's not even in the book, The wife called me last night and said the Honda was running ruff , hardley pull itself down the road, took her almost an hour to get home. Can any of yall give me any information about what im looking for. The code P1399 would be nice to know what im looking for.

Well, I don't guess anybody has any insight on that code, I know, it's not in the honda repair manuel, I guess i will take it to the honda shop monday. I beat my brane up on trying to figure this one out. Thanks again

then I would suggest pulling off the coil packs and looking for cracks. I would also suggest unplugging the coil packs 1 at a time to see if one of them is indeed bad. if you pull one and the engine idle gets worse(lower) then the coil pack is good. if the idle does not change then the coil pack is bad.

pull the front bank of plugs, inspect the gap. though its unlikely that it would be the only problem, as youd see gas mileage go to crap before it would cause the car to barely run.

gap is usually .44 for honda engines. I think service limit is .60-.64? someone correct me if im wrong. my buddys mazda used .44, and when his gap got to .68 it would barely run under heavier throttle.

I pulled each coil pack one at a time, nothing changed, It's going to the honda dealer monday so they can find out whats wronge with it, I put new plugs, Cleaned and replaced the EGR valve, new catalytic converter & O2 sensor,, Im done with it, It's been a great car, she bought it new in 2000, like anything mechanical, things go wrong.
Thanks for the information.

you put in all that money just to find the problem with no real diagnoses? that's just a shot in the dark, throwing money down the drain hoping you're right. I would be upset if I did that and nothing worked. which I'm sure by now you are.

I would have at least done a pressure test or leak down if I went through the injectors, spark plugs, and vacuum lines and found nothing before spending all that money on what you did.

good luck man.

Guys, I did a compresison test and checked the fuel pressure also Everything was close enough to spects on the compres test, I worked for chevy for 23 years as a mechanic. This is not my first rodeo with a car.without a diag scope, My little scanner don't stand up to a real scope.
Thanks again.

In testing the compression, It was between 164 & 157 PSI, The fuel pressure is 45 psi, As far at the cat & O2 sensor, I was gatting a p0420, and decided to change the cat & o2 sensor, Not being at a dealer anymore, I didn't have the equipment to test the injectors. And don't knock my being a chevy mech for 23 years, My chevy truck has 2 47000 miles on it and doesn't use or drop any oil, It is also running 75 psi oil pressure on a 95 deg day, I do take care of my cars.

Like said above your ignition system should be checked first but also check your MAP sensor. It doesn't seem like a likely cause but according to identifix, this has been found to fix the problem even with no codes thrown for a faulty MAP sensor. I would honestly save that for later. Try taking her to a dealer and find out which cylinder(s) actually have the misfire. This should lead you very close to your problem. Don't have them fix just get misfire data for ya
